Cargo War Risk Insurance 2026: Practical Guide for B2B Shippers

We are arranging shipments through three active war zones simultaneously right now, something I have not seen in fifteen years of freight operations. The Red Sea corridor, the Strait of Hormuz, and Eastern European transit routes are all flagged by underwriters at this moment. When we started quoting clients in early 2026, the first thing we learned was that their standard cargo policies covered almost none of the relevant risks. The gap between what shippers assume they have and what their policy actually covers has turned into a genuine financial threat. This guide explains the mechanics of war risk insurance for B2B shippers, what current premiums look like across active zones, and how to buy coverage without overpaying or leaving gaps.

What Standard Marine Cargo Insurance Does and Does Not Cover

Standard marine cargo insurance, whether written on Institute Cargo Clauses (A), (B), or (C), covers physical loss or damage caused by perils of the sea: storms, vessel sinking, collision, theft during transit, fire, and similar events. These clauses are the foundation of most freight insurance programs.

What they explicitly exclude is war risk. The Institute War Clauses for Cargo create a clean separation: any loss or damage caused by war, civil war, revolution, insurrection, hostile acts by belligerent parties, mines, torpedoes, bombs, or similar weapons falls outside the base policy. Capture and seizure are also excluded. The practical effect is that if a vessel carrying your cargo is struck by a drone, detained by a naval force, or rerouted due to active hostilities, your standard policy pays nothing.

This exclusion is not buried in fine print. It is a standard, well-documented feature of marine cargo policies worldwide. The problem is that shippers who have never shipped through a conflict zone often do not check until they have to.

Other notable exclusions in standard policies include:

• Loss caused by delay (even delay caused by war-related rerouting)
• Loss of market or consequential losses
• Inherent vice of the cargo
• Loss caused by intentional damage by the shipowner

When we review a client's insurance certificate before booking a Gulf transit, we always look for the war risk endorsement first. If it is absent, the cargo moves uninsured against the most relevant current threats.

What War Risk Insurance Actually Covers

War risk insurance is purchased as a separate endorsement attached to the standard cargo policy, or as a standalone placement. According to SeaRates' 2026 industry guide, a standard war risk endorsement for cargo covers three main categories of loss:

1. Physical damage from military action, damage to cargo caused directly by weapons, explosions, or military equipment during hostilities
2. Capture and seizure, cargo detained, confiscated, or seized by a governmental, military, or paramilitary authority
3. Acts of a belligerent party, damage arising from the actions of any party engaged in armed conflict, regardless of whether war has been formally declared

Some placements also include coverage for abandonment, if a vessel is ordered to leave a port or zone and cargo cannot be recovered, the policy responds. Coverage for general average contributions arising from a war-related incident is sometimes included as well, depending on the wording.

What war risk insurance generally does not cover:

• Delay or consequential loss (even if caused by a war event)
• Loss caused by government authorities of the cargo's country of origin or destination
• Nuclear, chemical, or biological weapons (typically excluded separately)
• Cyber attacks used as a weapon of war (emerging exclusion, varies by underwriter)

The coverage is typically written on a per-voyage basis for high-risk routes, or as an annual open cover with war risk extensions for shippers with regular volume. Underwriters can cancel or amend war risk coverage on short notice, the P&I club circulars in this cycle cite 48 to 72 hours, this is a standard market condition that shippers learn about the hard way when a zone escalates.

The Three Active War Zones in 2026 and Current Premium Levels

The insurance market in 2026 is pricing three concurrent active zones, and each has its own premium structure and availability picture.

The Strait of Hormuz and Gulf Transit

This is the most severe scenario of 2026 from an insurance standpoint. After the first attacks of late February 2026, Gulf war risk premiums rose roughly fivefold within 48 hours, and they kept climbing: at the peak, Bloomberg put Hormuz war risk at around 5 percent of vessel value, so a single $100 million tanker faced a war risk bill near $5 million for one transit. S&P Global reported in March 2026 that the strait was effectively closed to commercial shipping, and Allianz estimated roughly $125 billion of ships and cargo sat in the strait when it closed.

P&I coverage, the liability insurance that shipowners carry and that sometimes protects cargo interests indirectly, was cancelled for Iran and the Persian and Arabian Gulf effective 00:00 GMT on 5 March 2026, with clubs including Gard, West of England, and the Japan P&I Club issuing notices. This is significant because it means vessel operators that continue to transit are doing so without the standard liability layer, which affects how claims are handled and what recourse shippers have when cargo is damaged.

The cost did not stay with the shipowner. Hapag-Lloyd reported an extra $40 to $50 million a week in costs from the conflict, with some of its vessels stranded inside the Persian Gulf, and costs like that migrate into surcharges and rates. A widely floated fix, a roughly $40 billion US government war risk facility routed through the Development Finance Corporation, did not actually function: as of mid-2026 not a single policy had been written under it, and the parallel question of a public backstop remained open at EU level after a European Parliament question in March 2026.

According to Lloyd's of London, war risk insurance for the Hormuz corridor remains available, but at these elevated premiums. The London market has not withdrawn completely, which is significant, it means coverage can still be placed, but at a price that many shippers are not accustomed to paying. Howden Re reported in March 2026 that coverage reinstatement after initial cancellations was achievable, with prices elevated but showing some stabilisation, a stabilisation that is conditional on the conflict not escalating further.

Red Sea and Bab-el-Mandeb

The Red Sea corridor has been an active war risk zone since late 2023, and 2026 made it worse: in June 2026, Yemen's Houthis declared a maritime blockade of Israel-linked shipping across the Red Sea and the Bab-el-Mandeb strait. Coming on top of the Gulf crisis, that left underwriters pricing two chokepoints at once, with a large share of world container traffic and seaborne oil exposed to elevated war risk pricing simultaneously. By 2026 the market has developed specific Red Sea products with clearer triggers on what does and does not respond, but premiums remain far above pre-2024 levels.

Many shippers have already rerouted cargo around the Cape of Good Hope, which adds 10-14 days to Europe-Asia voyages. For those who continue using the Suez route, war risk endorsements are now a standard requirement rather than an option, and after the June blockade, securing them is harder and pricier than at any point since 2024.

Eastern European Transit Zones

Land-based and multimodal routes through Eastern Europe remain classified as war risk zones by most underwriters, and the maritime dimension sharpened in 2026: after tanker attacks in the Black Sea in January 2026, war risk rates there rose to roughly 1 percent of vessel value. Air cargo crossing certain airspaces attracts war risk endorsements as well. For shippers using rail corridors through or near conflict zones, the standard cargo policy exclusions apply in the same way as maritime coverage.

How to Buy War Risk Coverage: Step-by-Step

When we arrange war risk coverage for a client shipment, the process follows a consistent sequence. Here is how it works in practice.

1. Identify the routing before approaching underwriters. War risk pricing is voyage-specific. You need the vessel name or flight details, the port of loading, the port of discharge, the transit points, and the cargo description. Underwriters will not quote against a vague itinerary.
2. Confirm what your standard policy actually excludes. Pull the Institute Cargo Clauses wording and the war exclusion clause. Some policies have partial war cover built in for certain territories, you need to know exactly where your base policy stops before you go to a war risk placement.
3. Get declarations of cargo value and description ready. War risk underwriters need commodity type, packaging, declared value, and sometimes the shipper and consignee. Sensitive or dual-use cargo (electronics, chemicals) may attract additional questions or exclusions.
4. Request quotes from at least two markets. Lloyd's syndicates, specialist war risk underwriters, and your freight forwarder's bundle product (if available) can produce meaningfully different prices for the same risk. The difference can be 30-50% on a high-value shipment.
5. Confirm cancellation notice terms. War risk cover can be cancelled on very short notice, the P&I club circulars in this cycle cite 48 to 72 hours. Since most ocean voyages run far longer than that, ask about fixed-voyage endorsements that cannot be cancelled mid-transit, and confirm exactly which clause and notice period apply to your placement.
6. Get the endorsement in writing before the vessel departs. An oral quote is not coverage. The war risk endorsement must be attached to your policy and confirmed before the goods are loaded.
7. Keep the coverage certificate with your shipping documents. In a loss scenario, you will need to demonstrate continuous coverage from origin to destination. Gaps in documentation delay claims.

Lloyd's vs Standalone Broker vs Freight Forwarder Bundle, Which to Choose

There are three practical channels for buying war risk cargo insurance in 2026, and each has specific use cases.

Lloyd's of London Placement

Lloyd's of London remains the primary market for war risk insurance globally. The Lloyd's market brings together multiple syndicates that each take a share of the risk, which allows coverage to be placed even for high-value or complex shipments that a single insurer would not absorb alone.

For high-value cargo or routes with unusual risk characteristics, Lloyd's is usually the right answer. The documentation is thorough, the claims process is established, and the capacity is deeper than any alternative. The drawback is that accessing Lloyd's directly requires a Lloyd's broker, which adds a layer of cost and time. For a one-off shipment, the minimum premium floor at Lloyd's can make small parcels uneconomical to insure through this channel.

Standalone Specialist Broker

Several specialist war risk brokers operate outside the Lloyd's framework. They access capacity from markets including Lloyd's syndicates, company markets, and international reinsurers. For shippers with regular volume on high-risk routes, a specialist broker can set up an annual open cover with war risk extensions that automatically covers new shipments as they are declared.

This approach works well for mid-size freight operators who know their routing patterns in advance. The per-shipment paperwork burden is lower once the open cover is in place, and the broker can often negotiate better rates through volume.

Freight Forwarder Bundle

Many freight forwarders offer cargo insurance as part of their service package. Some of these products include war risk as a standard feature or an available add-on. FreightAmigo and similar platforms flag war risk surcharges as separate line items on the freight invoice, which hints at the underlying insurance structure.

The advantage is convenience, one vendor, one invoice, one point of contact. The risk is that bundled products may have sub-limits on war risk claims, geographic restrictions written into the fine print, or coverage that responds differently than a standalone policy. Before relying on a forwarder's bundled insurance for high-value or time-sensitive cargo, read the actual policy wording rather than the product brochure.

Our general guidance: for routine small-parcel shipments through mildly elevated risk zones, a forwarder bundle is acceptable. For container loads through active conflict zones, go to Lloyd's or a specialist broker.

War Risk Surcharges vs War Risk Insurance: Key Difference

This distinction causes confusion in nearly every client conversation we have about Gulf routing.

War risk surcharges are carrier fees. They are what the shipping line charges you to carry your cargo through a high-risk zone, covering the carrier's additional costs: higher insurance premiums for their vessel and hull, crew hazard pay, and operational complexity. Hapag-Lloyd has published a war risk surcharge of $1,500 per TEU for standard containers and $3,500 per container on affected routes, in force from 2 March 2026. This cost appears as a separate line item on your freight invoice.

Paying the war risk surcharge does not insure your cargo. The surcharge compensates the carrier for their elevated costs. If your cargo is damaged or lost due to a war event, the surcharge gives you no claim rights against the carrier and no insurance payout. You are simply paying more to ship through the zone.

War risk insurance is the coverage that pays you if your cargo is physically damaged, seized, or lost due to war-related events. It is purchased separately, from an insurance market, and it covers the cargo owner's interest, not the carrier's.

A shipper can pay the war risk surcharge and have no war risk insurance. A shipper can also buy war risk insurance and not pay a carrier surcharge (if the carrier does not apply one). In practice, in active zones like the Gulf right now, both apply simultaneously.

The surcharge is a cost of shipping. The insurance is protection against loss. They serve different functions and should be budgeted separately.

When War Risk Insurance Is Mandatory vs Optional

War risk insurance is not universally required by law or contract, but several scenarios make it effectively mandatory.

Letter of Credit Requirements

When a shipment is financed under a letter of credit, the bank almost always specifies insurance requirements in the documentary credit. Many LCs now explicitly require war risk coverage for shipments transiting active zones. The cargo cannot be tendered under the LC without a compliant insurance certificate. This has become a standard requirement for Gulf-bound cargo in 2026.

Buyer or Seller Contract Terms

Under CIF (Cost, Insurance, and Freight) Incoterms, the seller is responsible for arranging insurance to the port of destination. If the route passes through a war zone, a CIF seller who arranges only standard cargo coverage and omits the war risk endorsement is arguably in breach of their obligation to provide adequate insurance. Courts have found against sellers on this basis in post-loss disputes.

Carrier Requirements

Some carriers now require shippers to sign declarations confirming that cargo insurance arrangements are in place before accepting bookings for high-risk routes. This is a risk-management step by the carrier and does not create a direct obligation, but practically it means you cannot book the voyage without confirming coverage.

When It Is Optional

For shipments on routes that pass near but not through active zones, and for cargo of lower value where the shipper is willing to self-insure the war risk portion, the endorsement remains optional. Governments talked about stepping in as insurers of last resort during the 2026 peak, but the headline proposal, a roughly $40 billion US Development Finance Corporation war risk facility, never actually wrote a policy, and the question of a public backstop was still open at EU level in 2026. Even where such a scheme exists, it is built to keep the market functioning, not to pay individual cargo claims, it is a systemic backstop for market failure, not a substitute for your own policy.

For high-value cargo on any routing that passes within declared war risk zones, treating the endorsement as optional is a financial risk decision that should be made consciously, not by default.

FAQ

Q: Who is insuring ships in Hormuz right now?

A: The Lloyd's of London market remains the primary source of war risk coverage for vessels transiting the Strait of Hormuz, with syndicates writing the risk at elevated premiums and some company and specialist markets also active. A widely discussed US government backstop, a roughly $40 billion facility via the Development Finance Corporation, did not in practice write any policies, so private cover is what is actually holding the zone. On the liability side, P&I war cover for Iran and the Persian and Arabian Gulf was cancelled effective 5 March 2026 by clubs including Gard, West of England, and the Japan P&I Club, so vessels that continue to transit are doing so without the standard liability layer, and hull and war risk cover is being placed separately.

Q: What are the insurance premiums for the Strait of Hormuz in 2026?

A: Premiums rose roughly fivefold within 48 hours of the first attacks in February 2026, and climbed further as the strait effectively closed. Bloomberg put Hormuz war risk at around 5 percent of vessel value at the peak, which is about five times the level of the first days of the war and means roughly a $5 million bill for a $100 million tanker on a single transit. Rates vary by cargo value, vessel type, and underwriter, and underwriters expect the elevated band to persist for months rather than weeks, so get current market quotes rather than relying on historical benchmarks.

Q: Are insurance companies cancelling war risk coverage for vessels in the Gulf?

A: Yes. Clubs including Gard, West of England, and the Japan P&I Club cancelled war risk cover for Iran and the Persian and Arabian Gulf effective 5 March 2026, and there were reported cases of cover withdrawn mid-voyage that left cargo stranded with no immediate replacement. The short cancellation notice in war risk policies, the P&I circulars in this cycle cite 48 to 72 hours, is the mechanism that allows this. Reinstatement of hull and cargo war cover was available from March onward at higher prices, and the Lloyd's market continued to write throughout. The practical implication for shippers is unchanged: securing a fixed-voyage endorsement before departure, one that cannot be cancelled mid-transit, is worth the additional premium in active zones.

Q: Does paying a war risk surcharge to my carrier give me insurance?

A: No. The war risk surcharge charged by carriers like Hapag-Lloyd ($1,500 per TEU, $3,500 per container) is a fee that compensates the carrier for their elevated operating costs in the zone. It does not provide any insurance coverage for your cargo. If your goods are damaged or lost due to a war event, the surcharge payment gives you no claim rights. War risk cargo insurance must be purchased separately from an insurance market.

Q: Can I rely on my freight forwarder's cargo insurance for war risk coverage?

A: Possibly, but verify before relying on it. Some forwarder-arranged cargo policies include war risk as standard or as an add-on. Others exclude it entirely or apply sub-limits that may not match your cargo value. Before accepting a forwarder's insurance certificate for a shipment through an active zone, request the actual policy wording and confirm the war risk coverage limits, the exclusions, and the cancellation terms. Do not rely on a product summary or verbal assurance.

Q: What happens to cargo if the ship is rerouted due to war risk and the voyage takes longer?

A: Standard cargo policies and war risk endorsements generally do not cover delay or consequential losses, only physical damage, capture, or seizure. If a vessel reroutes around the Cape of Good Hope instead of transiting the Red Sea, adding two weeks to the voyage, and your cargo arrives late but undamaged, neither policy pays anything. The additional freight costs and any contractual penalties you incur from the delay are not covered by cargo insurance. Some specialty trade disruption or freight contingency products can cover delay costs, but these are purchased separately and are not part of a standard war risk endorsement.

Conclusion

The gap between standard marine cargo coverage and what is actually needed for 2026 routing has become commercially significant. Premiums that climbed to roughly 5 percent of vessel value with the strait effectively closed, P&I war cover cancelled in the Gulf, a two-front crisis that by June 2026 also engulfed the Red Sea, and carrier surcharges that do nothing for cargo owners have combined to leave any shipper who has not updated their insurance arrangements in the last 12 months carrying uninsured war risk exposure.

The steps are straightforward: confirm what your standard policy excludes, identify your routing through any flagged zone, and place a war risk endorsement before the goods are loaded. The Lloyd's market remains open. Coverage is available. The question is whether you have arranged it.

When we set up new client accounts for Gulf-bound cargo today, the war risk endorsement is the first document we request, not the last. That order of operations has saved several clients from learning about the exclusion after a loss event rather than before one.
